The National Corporate Party wished to establish a corporate state in Ireland and was strongly anti-communist.[1] Its military wing was the Greenshirts.[1] It failed to gain much support however, with the majority of Fine Gael members remaining loyal to that party and O'Duffy only securing a handful of loyal supporters for his group.[2]

O'Duffy left Ireland in 1936 to become involved in the Spanish Civil War, a fact which led to further decline in the National Corporate Party.[2] The party was defunct by 1937.[1]
